AbstractWe update the constraints on the cosmological parameters by adopting the Planck data released in 2015 and baryon acoustic oscillation (BAO) measurements including the new DR14 quasar sample measurement at redshift z = 1.52, and we conclude that the six-parameter Lambda CDM model is preferred. Exploring some extensions to the Lambda CDM model, we find that the equation of state of dark energy reads w = -1.036 +/- 0.056 in the wCDM model, the effective number of relativistic degrees of freedom in the Universe is N-eff = 3.09(-0.20)(+0.18) in the N-eff + Lambda CDM model and the spatial curvature parameter is Omega(k) = (1.8 +/- 1.9) x 10(-3) in the Omega(k) + Lambda CDM model at 68% confidence level (C.L.), and the 95% C.L. upper bounds on the sum of three active neutrinos masses are Sigma m(v) < 0.16 eV for the normal hierarchy (NH) and Sigma m(v) < 0.19 eV for the inverted hierarchy (IH) with Delta chi(2) =chi(NH) (2) - chi(IH) (2) = -1.25.
